ConclusionsThis study provides information about Aβ plaque burden, tau tangle burden, and neurodegeneration in cognitively unimpaired persons at three levels of genetic risk for AD. Unimpaired APOE ϵ4 HMs can be studied before their 70s to evaluate the understanding of factors, processes, and interventions involved in the predisposition to and prevention of AD, and after their 70s, to discover factors, processes, and interventions involved in the resilience or resistance to and prevention of AD.

Publication date: Available online 9 December 2019Source: European Annals of Otorhinolaryngology, Head and Neck DiseasesAuthor(s): A. Attyé, M. EliezerAbstractEndolymphatic hydrops features excess endolymph in the membranous labyrinth, and is a marker of Menière's disease. Between the early 1980s and late 2000s, MRI in Menière's disease aimed purely to rule out tumor or malformation as differential diagnoses for the pressure disorder. Progress in high-resolution MRI, however, now enables excess endolymph to be visualized in the membranous labyrinth, differentiating saccule and utricle in Menière...

In this study, we compared different anesthesia and operation methods for modeling VX2 hepatocarcinoma in rabbits. Forty New Zealand white rabbits were randomly divided into three groups: A, B, and C. Group A underwent ultrasound-guided implantation and intravenous anesthesia; Group B underwent ultrasound-guided implantation and inhalation anesthesia; Group C underwent laparotomy implantation and intravenous anesthesia. Anesthesia and operation differences were compared between groups A and B, and A and C, respectively. We used magnetic resonance imaging (MRI) to assess tumor formation and growth, and pathological examinat...

ElwingAbstractPurposeTargeted treatment for pulmonary arterial hypertension (PAH), diagnosed via right heart catheterization (RHC), has been shown to improve morbidity and mortality. Identifying characteristics that predict clinical worsening has been challenging. We sought to evaluate the role of cardiac Magnetic Resonance Imaging (CMR) as a predictor of clinical worsening in a cohort of treatment-naïve pulmonary hypertension (PH) patients.MethodsWe performed a r...

Ann Yeh, Brenda Banwell, Amit Bar-Or, Douglas L. Arnold, Canadian Pediatric Demyelinating Disease NetworkAbstractIn conventional non-quantitative magnetic resonance imaging, image contrast is consistent within images, but absolute intensity can vary arbitrarily between scans. For quantitative analysis of intensity data, images are typically normalized to a consistent reference. The most convenient reference is a tissue that is always present in th...

Publication date: Available online 9 December 2019Source: NeuroImageAuthor(s): Erik D. Fagerholm, Rosalyn J. Moran, Inês R. Violante, Robert Leech, Karl J. FristonAbstractModels of coupled phase oscillators are used to describe a wide variety of phenomena in neuroimaging. These models typically rest on the premise that oscillator dynamics do not evolve beyond their respective limit cycles, and hence that interactions can be described purely in terms of phase differences. Whilst mathematically convenient, the restrictive nature of phase-only models can limit their explanatory power. We therefore propose a generalisati...

AbstractObjectiveTo assess interobserver reproducibility of different regions of interest (ROIs) on multi-parametric renal MRI using commercially available software.Materials and methodsHealthy volunteers (HV), patients with heart failure (HF) and renal transplant recipients (Tx) were recruited. Localiser scans, T1 mapping and pseudo-continuous arterial spin labelling (pCASL) were performed. HV and Tx also underwent diffusion-weighted imaging to allow calculation of apparent diffusion coefficient (ADC). For T1, pCASL and ADC, ROIs were drawn for whole kidney (WK), cortex (Cx), user-defined representative cortex (rep-Cx) an...

ConclusionsThe limited currently available evidence shows potential of certain MRI settings for the use in operative dentistry. Further research needs to assess the applicability and accuracy for dental hard tissues as well as cost-benefit aspects of the MRI technique.Clinical relevanceCertain MRI settings may have the potential as diagnostic tool in operative dentistry.
